Link AB rotates counterclockwise (CCW) from the position shown below to horizontal (0 degrees) with ω = 12 rad/s and α = 5 rad/s^2. Draw the mechanism for the second condition. Find I23.13 and I34.13. Find ICs, W3, and W4 for the second condition, using the analytical method and IC method. θ2 = 32.56 degrees, θ3 = -13.8 degrees, θ4 = 132.1 degrees.
To find I23.13 and I34.13 for the second case, use the sine rule: sinA/sinB = a/b = c.
